Modern Vespa

Hello all, are there any x10 experts here? Specifically to do with the abs and asr? Iv got a very unusual problem that i just can get to the bottom of
Basically the abs and asr lights flash continuously, while like this it will only accelerate a bit then cuts all power, i assume this is traction control cutting the power
If i turn the asr off (light on permanently) the abs light still flashes and i have full power and rides as normal, it wont do an asr calibration, will go into calibration mode i think, but just stays in it for a couole of minutes, then goes back to how it was and no reset
Its like its just permanently reading wheel slip so wont do anything else
Speedo works too
Any help would be hugely appreciated even if on an asr system thats not on the x10

Thanks all!

Trust me. Check your tire pressures.

First thing i checked! They were out so set them to the manual, i had a ride today and its developed into an abs light on constantly now, so ill go and get it plugged in, think it might of been a wheel sensor going bad, well i hope it is at least!

If it's any help, some X10 workshop manuals are here: https://manuals.wotmeworry.org.uk/Piaggio/Piaggio%20X10/
